Abstract: A system detects a screen tear in a display device for frames of video by retrieving an identification code associated with each pixel row of the frame of video and analyzing identification codes across the pixel rows of the frame of the video to detect occurrence of a screen tear. To support compressed (e.g., lossy) video data, the identification code associated with each pixel row of the frame of video is inserted into the most significant bit (or bits) of a color channel of a first pixel of the pixel row. Identification codes across the pixel rows of the frame of the video are then compared for tear detection. Because modification of the most significant bit of a color channel of a pixel may result in color distortion, the pixels including inserted identification codes are hidden from view by the display device.

Abstract: A method of increasing temporal resolution: a) provides an original video having a given spatial resolution; b) compresses a first frame of said original video using any image compression method; and c) repeatedly compresses a next frame of said original video using the steps of: i. providing a current video comprising the already compressed video frames, said current video having an initial spatial resolution; ii. repeatedly reducing the spatial resolution of said current video and the spatial resolution of said next frame of the original video, to produce a lowest level spatial resolution current video and a lowest level spatial resolution next frame of the original video; and iii. compressing said lowest level spatial resolution next frame of the original video to produce a lowest level compressed next frame.

The processor is to execute an intra block copy prediction on the video frame to generate intra-block-copy candidates.

The processor is to further also execute a final mode decision based on a comparison of the rate distortion optimization (RDO) costs.

Abstract: A video block of a current picture may be coded in an intra block copy (IBC) mode. Weighted prediction may be disabled for the IBC-coded screen content video block. Fractional block vectors may be used for the chroma components of the IBC-coded video block. An interpolation filter may be utilized to generate chroma prediction samples for the video block. A decoded version of the current reference picture may be added to both reference picture list L0 and reference picture list L1 that are associated with the IBC-coded video block. When constrained intra prediction is applied, reference samples that may be used to predict an intra-coded video block may be limited to those in intra-coded neighboring blocks. The range of IBC searches may be restricted by imposing a maximum absolute value for block vectors.

Abstract: In a particular implementation, a clipping bound may be different from the signal bound. For example, to derive the upper clipping bound, a reconstructed sample value corresponding to original sample value Y is estimated to be Y+?y. Thus, for a candidate upper clipping bound x, the difference between the clipped value and the original value is calculated as min(Y+?y, x)?Y. The distortions using different candidate clipping values around signal bound M may be tested. The test starts with signal bound M and moves towards smaller values. The distortion may first decrease (or maintain the same) and then increase, and the turning point is chosen as upper clipping bound M?. Similarly, the lower clipping bound m? can be chosen. For more effective clipping, the color components may be transformed such that the transformed color components may be more tightly enclosed by a box defined by the clipping bounds.
